Nano cesium tungstate is new material which is discovered recently. Some painting company in Japan, Germany and America are aimed at developing cesium tungstate transparent heat insulating painting. Nano cesium tungstate is a kind of inorganic nano powder which has good absorption capability toward near infrared.

Cesium tungstate, which chemical formula is Cs2WO4, is colorless crystal, has strong absorption for moisture. It has phase turn around at 536℃ from rhomboidal crystal to hexagonal crystal, soluble in water.

Cesium tungstate has transparent heat insulating property while in near infrared area (wavelength 800~1100nm), and strong penetrating property in visible area (wavelength 380~780nm), strong shielding property in violet light area (wavelength 200~380nm). As a result, nano cesium tungstate has adorable near infrared absorption, visible light transmission property, has wide application prospect in window heat insulating, car membrane, sunlight insulating and so on.

Cesium tungstate producing method including solid phase method, liquid phase co-precipitation method, micro-emulsion method, hydrothermal method, etc.. However, the shortcomings during producing process such as high cost, low producing efficiency results it in high price.

To date, there are few research on nano cesium tungstate producing method national wide, China is in the leading place instead. To be honest, there are many shortcomings while during producing process, it is hard to be applied in a wider field due to its high cost. But with progress made in research and former experience, more preparation methods will come out in the future.
